DETACHABLE BOOK-COVER.

Specification of Letters Patent.

Patented Feb. 24, 1914.

Application filed June 9, 1910, Serial No. 566,255. Renewed July 24, 1913. Serial No. 781,258.

To all whom it may concern Be it known that I, HENRY G. FOLGER, a citizen of the United States of America, and a resident of .Somerville, in the county of li liddlesex and State of Massachusetts, have invented certain new and useful Improvements in Detachable Book-Covers, of which the following is a specification.

This invention relates to detchable covers for books and is particularly designed for use in connection wit-h paper covered books such as telephone directories which are in constant use and are changed from time to time for new editions.

The particular object of the invention is to provide a detachable cover which will protect the book and provide a ready means for the suspension thereof from a hook.

The invention consists of a peculiar means of locking the boo-k to the detachable covers. This means includes certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents an inner elevation of the covers and binding members, the covers being spread open. Fi 2 represents a section through the same, the cutting plane being on line 22 on Fig. 1 and a portion of one of the covers being shown in elevation. Fig. 3 represents a horizontal section of the same drawn to an enlarged scale, the cutting plane being on line 3--3 on Fig. 2, and Fig. 4 represents a horizontal section through the binding strip and showing its co-acting locking bar in plan, the cutting plane being on line H on Fig. 1.

Similar characters designate like parts throughout the several figures of the drawmgs.

In the drawings, 10-10 represents the sides of a book cover and 11 represents the back portion thereof, said sides and back portion being made of any well-known material and connected together in the usual manner by means of cloth facings 12 and 13 secured to the sides and back by any suitable adhesive material, thereby forming the joints 14 permitting the side portions 10 to be moved into positions in alinement with the back portion 11 or at right angles thereto.

Secured to the back portion 11 by some suitable means such as the cloth strip 15 glued to or otherwise secured to the back portion 11 and sides 10 is a bar 16 having an upper car 17 and a lower ear 18 at right angles thereto. The lower strip is provided with a slit 19 extending therethrough while the upper ear is provided with a similar slit 2O somewhat longer than the slit 19. This slit 20 in the'upper car 17 has branching therefrom a narrow slit 21 extending to the edge of the ear 17, as is clearly indicated in Fig. vof the drawings. A thin strip 22, preferably of metal is inserted through the slits 20 and 19 and has a shoulder thereon such as the bent-over portion 23 at its lower end, which engages the under face of the lower ear 18 and prevents the strip 22 from being lifted upwardly. The upper end of this strip 22 is provided with an opening 24 therethrough, the lower edge of which is in alinement with the upper face of the ear 17 Through this hole or opening 24 is a suspending ring 25 by which the book may he hung from the hook whennot in use. When the book is to be inserted, it is opened up and the strip22 removed from the car 17 through the slit 21 and inserted between two of the leaves in the center of the book and then the strip 22 is again inserted through the slit 21-into theslit'20 and the book is then held securely to the covers, the shoulder 23 preventing any movement of the strip in one direction while the ring 22 prevents any movement of the strip 22 inthe opposite direction.

As will be observed by reference to Fig. 4'

order to accomplish its removal through the slit 21. This makes a very simply constructed detachable cover for telephone directories and similar books which may be used for advertising purposes if desired and the inner faces of the cover maybe utilized for the insertion of special numbers most usually called for by the subscriber.

It is. believed that the many advantages of the invention will be fully understood from the foregoing.

Having thus described my invention, I claim: 1

1. In a device of the class described, the combination of a pair of covers; a bar secured thereto having an ear at each end the lower of which is provided with a straight slit while the other is provided with a similar slit having a lateral slit extending therefrom to the edge of said ear; a thin strip extending through said slits and provided with a shoulder at its lower end engaging the lower ear; and means extending through the upper end of said strip to prevent its displacement.

2. In a device of the class described, the combination of a pair of covers; a bar secured thereto having an ear at each end the lower of which is provided wit-h a straight slitwhile the other is provided with a similar slit having a lateral slit extending therefrom to the edge of said ear; a thin strip extending through said slits and provided with a shoulder at its lower end engaging the lower ear; and a ring extending through the upper end of said strip to prevent its displacement.

3. In a device of the class described, the combination of a pair of covers; a bar secured thereto having an ear at each end the lower of which is provided with a straight slit while the upper is provided with a slit having its walls substantially parallel to the walls of the first slit and having a lateral slit extending therefrom to the edge of said ear; a thin strip extending through said slits and provided with a shoulder at its lower end engaging the lower ear; and means extending through the upper end of said strip to prevent its displacement.

4. In a device of the class described, the combination of a pair of covers; a bar secured thereto having an ear at each end the lower of which is provided with a straight slit while the upper is provided with a corresponding slit having its walls substantially parallel to the walls of the slit at the lower end and having a lateral slit extending therefrom to the edge of said ear, the walls of said slits in the upper end being slightly cut away at their junction; a thin strip extending through said slits and provided with a shoulder at its lower end engaging the lower ear; and means extending through the upper end of said strip to prevent its displacement.

5. In a device of the class described, the combination of a pair of covers; a bar secured thereto having an ear at each end the lower of which is provided with a straight slit while the upper is provided with a corresponding slit having its walls substantially parallel to the walls of the slit at the lower end and having a lateral slit extending therefrom to the edge of said ear, the walls of said slits in the upper end being slightly rounded off at their junction.
